This Relação is incontestably the first book (in reality a pamphlet) printed in Brazil.

Apart from the Relação da Entrada, the Aplauso, and the Conclusiones Metaphysicas, Antonio Isidoro da Fonseca printed in Rio de Janeiro twelve others leaves bearing eleven Latin epigrams and one Portuguese sonnet, each work on a separate unumbered leaf.

It is not known whether Antonio Isidoro da Fonseca printed anything else. However, it is supposed that he did not, for on 5 July 1747 (the same year as the Relação da Entrada was published), the government in Lisbon issued a "Provisão" which read:
"Whereas, it is said, that from this Kingdom a quantity of typographic letters have gone to Brazil; and Whereas, it is considered that there is no advantage for the printers to work now in Brazil where expenses are heavier than in the Kingdom [of Portugal]. Books and papers can be printed here in the Kingdom and sent to the colony; and Whereas, the authorization to print, both on the part of the Inquisition and on the part of my Overseas Council, must come from the Kingdom, and these authorizations have to accompany all printed papers.

Without said authorization it is forbidden to print or sell any work; and Whereas, it has been made known that some printing types are now within the limits of your jurisdiction; Now Therefore, I order them to be confiscated and remitted to my Kingdom, at the expense of their proprietors. They may be delivered to anyone according to the wishes of the proprietors. You shall notify the proprietors of the said types, and all printing officials, that it is forbidden to print books, works or any loose leaf papers even if a prior authorization for this purpose has already been issued to them. The breaking of this order will be punished by sending the culprit or culprits to my Kingdom to appear before the Overseas Council which will pass sentence on them, in accordance with the crime committed. Notify on my behalf the "judges" [ouvidores] and ministers of this order of mine that they may enforce it and register it in all their courts. …"

This "Provisão" ended the activities of Antonio Isidoro da Fonseca in Brazil. He returned to Lisbon, and in 1750 made a request to return to Brazil to establish printing. To his petition the Judge pronounced a laconic "excusado", implying that it was "hopeless" to pursue the matter further.

Nothing else is known today about the founder of the press in Rio de Janeiro. No other printing establishment existed in Brazil until 13 May 1808, when the Imprensa Régia started to operate.

The Relação da Entrada, "obra volante" and illicit, could not have been issued in many copies. It is even possible that the closing of the printing house resulted in the loss of part of the edition. The fact remains that very few copies have come down to us. I know of the existence of no more than five or six copies. Of these, three are in Brazilian public libraries (two in the National Library and one in the Ministry of Foreign Affairs). The two copies in the National Library in Rio de Janeiro are of different issues; the first has a misprint in the last word of the line below the author's name: "uurzentes", and the second copy has the misprint corrected: "Auzentes." [The latest is the JCB copy].

In the copy in the Ministry of Foreign Affairs the date is misprinted: M.CC.XLVII instead of M.DCCXLVII. It may be surmised that at least three states of the Relação exist, but an accurate comparison between all the known copies will reveal more interesting details about this first book printed in Brazil.
